My partner and I stayed at the Mustang Nero while traveling Thailand for our honeymoon. Our flight arrived early morning, and we couldn't check in until hours later. They were very welcoming and accommodating, holding our bags so we could explore until check in time. They did the same when we checked out as well, including calling a cab for us to take us to the train station. Our stay here was lovely, and the breakfast is incredible. It's a great area of Bangkok, and is a short walk to the Sky Train. You have to check out W Market across the street at night. I would absolutely recommend Mustang Nero for your stay, and would stay here again if visiting Bangkok.
